TPCM 780 Series

Phase Change Materials

TPCM 780 Series

Tpcm 780 is a high performance, inherently tacky, easy to rework phase change thermal
interface material. Developed specifically to meet the high thermal conductivity and low
thermal resistance requirements of today’s demanding processors.

This silicone-free material is so soft that it begins to flow as the temperature is elevated by
just a small amount. Also, since no tabs are required, Tpcm 780 eliminates the need for
expensive converting.

• Minimizes contact thermal resistance by filling the microscopic irregularities

of the components it contacts. Begins to soften and flow at approximately 45ºC

• Designed to minimize migration (pump out) at CPU operating temperatures

using a unique material formulation that softens, but does not fully change phase

• Silicone-free for applications that are silicone sensitive

• Outstanding thermal performance helps to ensure CPU/application reliability

• No mess due to thixotropic characteristics which prevent flow outside of interface

• Very soft at room temperature, therefore less stress on board during assembly

• Tabless parts make for easier handling in the manufacturing environment

• RoHS Compliant

• 94V0 UL Flammability Rating

• Naturally tacky at room temperature, requiring no adhesive

• Heat sink preheating not required

• Exceptionally high reliability during storage and after installation

Applications • Graphics Cards
• Notebooks
• Desktops
• Servers
• Memory Modules
• Automotive
